Lightweight Pulley Kit: Worth It ? Underdriven Or Not ?

[cobrAA]

Hey guys,

Considering raw and KTS sell their pulley kit for about 200$, I though I could grab a set if they do provide quicker acceleration.

My second question is.. should I buy a set who use the same dimension as OEM or one that is underdriven ?

You're talking shout two tenths of nothing but I Spose every little but helps.

How high are you revving it the engine? Having -5's hanging off the side of it, it won't be 10,000 rpm do stay standard size.

you heard me through my last thread.. my goal is to stay with the -5s and rb26 and try to make the best out of it. I could go stroker or EFR but my actual setup is doing fine so I dont feel like dropping another 5-8k when everything is fine lol Still powerful and quick enough to go over the spped limit in no times

Think about how much it takes to accelerate a car,then compare that to how much it takes to accelerate the pulleys on your engine.

I would say the gain would be less than 2 tenths of nothing!

Like your comparaison done deal. will put the money toward something else.

Yep. A lightened flywheel will save 4-5kg, and that's noticeable. Lightened pulleys are going to be a small fraction of that.

Underdrive pulleys are generally for ball-tearing racecars...when you're trying to squeeze every last bit from a car that already has no interior, no aircon, no glass, and half the bolts it was built with.
